IOWA CITY — The Army Corps of Engineers began increasing the amount of water flowing out of the Coralville Lake Reservoir Wednesday.

A Johnson County Emergency Management news release said the flow would increase from 10,000 cubic feet per second to 12,000. It will continue at this stage until Coralville Lake levels begin to fall more than a foot per day, according to the release.

While small amounts of rainfall are expected over the next day, the National Weather Services has forcasted no rain over the next seven days, according to the release.

“Obviously this is good news with predicted lake elevations dropping below 711 feet and outflows decreasing to less than 13,000 CFS from the dam. No mandatory evacuations are anticipated due to these changes,” said Dave Wilson, Johnson County Emergency Management director, in the release.

Because of flooding threats, voluntary evacuations are recommended for some areas of unincorporated Johnson County at Camino Del Rio SE, Driftwood Lane SE and Ocean Boulevard SE, according to the release.
